Palm Beach is home to thousands of families where one spouse is a U.S. citizen, another holds a green card, and children may hold a mix of statuses. For these mixed-status households, estate planning is not a routine errand. The wrong document, or the absence of one, can trigger federal estate tax, freeze assets a surviving spouse needs, or leave a child’s guardianship to a judge who never met the parents. Florida law and federal immigration rules intersect in ways that surprise even careful families, and getting them to work together takes deliberate planning.
The Non-Citizen Spouse Problem
Most married couples assume that anything left to a surviving spouse passes free of federal estate tax. That is the unlimited marital deduction, and it is one of the cornerstones of American estate planning. But there is a catch that catches many Palm Beach families off guard: the unlimited marital deduction is generally not available when the surviving spouse is not a U.S. citizen. Congress was concerned that a non-citizen spouse might inherit a large estate and then leave the country before any tax could be collected.
The standard solution is a Qualified Domestic Trust, or QDOT. Property passing to a non-citizen spouse through a properly drafted QDOT can still qualify for the marital deduction, deferring estate tax until distributions are made from the trust or the spouse dies. A QDOT must meet specific requirements, including having at least one U.S. trustee with authority over distributions. This is technical drafting that belongs in your Florida trust documents under Chapter 736, and it should be revisited if the non-citizen spouse later naturalizes, because citizenship can remove the need for the QDOT entirely.
Estate Tax Exposure for Non-Resident Owners
Status also shapes how much of an estate is exposed to federal tax in the first place. A U.S. citizen or domiciliary is taxed on worldwide assets but enjoys the full federal exemption. A non-resident alien who owns U.S. situs property, such as a Palm Beach condo or shares in U.S. companies, is generally taxed only on those U.S. assets but receives a dramatically smaller exemption. Snowbirds and foreign investors who buy Florida real estate without planning can leave their heirs facing a tax bill on property they assumed would simply pass to the family. Coordinating ownership structure with an estate plan, rather than after the fact, is what prevents that outcome.
How Status Affects Beneficiaries and Inheritance
A common myth is that a non-citizen, or even an undocumented family member, cannot inherit in Florida. That is false. Florida’s intestacy and probate rules do not bar heirs based on immigration status, and a properly executed will under section 732.502, signed before two witnesses, can leave property to anyone. What status does affect is logistics: a beneficiary abroad may struggle to administer assets, claim homestead, or serve as personal representative. Florida’s homestead protections, which shield a primary residence from most creditors and pass it outside the probate estate, apply to the property and the surviving spouse and heirs regardless of citizenship, but they interact awkwardly with trusts and must be planned around, not assumed.
Guardianship, Powers of Attorney, and Travel
For immigrant parents, naming a guardian for minor children is among the most urgent steps. If both parents are detained, deported, or pass away, a guardianship designation in your estate documents tells a Florida court whom you trust to raise your children, instead of leaving that decision to strangers. Equally important is a durable power of attorney and a health care surrogate. Clients frequently travel abroad for consular interviews, visa stamping, or to gather documents for a pending case, and a power of attorney lets a trusted person manage finances and sign for the family while they are out of the country.
Coordinate Both Sides of the Plan
Because we handle estate planning and not immigration matters, we work alongside immigration counsel so the two plans reinforce each other. A pending green-card or naturalization case can change which trust structures make sense and when, and a family with petitions in process should have family-based immigration guidance running in parallel with their estate documents. For the immigration side of these questions, we routinely refer Palm Beach clients to a Miami immigration attorney who understands how status decisions ripple into inheritance.
Newcomers to Florida need both an estate plan and immigration counsel, not one or the other. If your household includes a non-citizen spouse, foreign-owned property, or children whose future depends on a pending case, contact our Palm Beach office to build a plan that protects your family on both fronts.
